Just got a new imac, transfered evereything trough TM backup, mostly everything looks good, apart from the Mail, i got 4 different accounts, but one one of didnt download all the mails, and stopped at november last year. When i try to open account settings for that account, i get a message "cant connect, please enter password" and when entering that, it wont accept the password i know is correct. Sending a test mail, works fine both in and out. What is wrong, or what can i do? I got too much valuable mails in that account to delete and create new one. Its a POP mail. Solved!
